Hello. may be it is too late for reply this, but I had a museum piece
like this portable, if helps here is the power pin out:
1- yellow- (+12 v)
2-orange- power good PG (+5v)
3-N/C
4 to 8- black- ground
9 to 12-red - (-5v)
13 - blue (-12v)
Unfortunally I do not have the plasma display tensions and power
connections. If sombody has it, please share with us.
Good luck...Jorge
